CORD-TIP.

SPECIFICATION forming part of Letters Patent No. 738,545, datedSeptember 8, 1903.

Application filed June 6, 1902. Serial No. 110,431. (No model.)

To all whom, it may concern:

Be it known that 1, WILLIAM KAISLING, a citizen of the United States ofAmerica, and a resident of Chicago, county of Cook, and State ofIllinois, have invented a certain new and useful Improvement inCord-Tips, of which the following is a specification.

Myinvention relates to improvements in metallic tips for electricconductors, said tips being adapted more particularly for clothvcoveredconductors intended for use with be convenient and inexpensive tomanufac ture.

In the accompanying drawings,which illustrate the invention, and inwhich the same reference characters are used throughout the severalviews for like parts, Figure 1 is a general View of the receiver-cordprovided with my improved tips. Fig. 2 is a view showing the detachedparts of the tip and the end of the conductor. Fig. 3 is a perspectiveView showing the clamping-clip in position, but before being clampedupon the end of the conductor. Fig. a shows the same after being clampedin position, and Fig. 5 is a 1ongitudinal section showing the deviceupon an enlarged scale and secured in place.

The receiver-cord consists, as usual, of a pair of cloth-coveredconductors 2 2, with a supporting-cord 3, formed from the reduced end ofthe inclosing sheath 3. The conductors or cords 2 2 are provided withmetallic tips 4, each having the sleeve portion 5 adapted to be slippedover and to envelop the end of the conductor 2 and to be electricallyconnected with the plurality of fine wires 6, constituting the metalliccore of the conductor.

The pin 7 of the tip 4 is formed integrally with the sleeve 5 and isreduced in diameter to enable it to enter the usual aperture in a commonbindingpost or other device with which the tip and cord are employed.

Fig. 2 shows the several parts of the device more in detail. The end 6of the strand of fine wires is stripped of the cloth or other insulatingor protecting covering for a short distance-that is, the cloth coveringis cut away or otherwise removed-and the clamping-clip 8, consisting ofa stamping of thin sheet metal tinned and having V-shaped notchedinterengaging edges, as shown, and formed into U shape, is placed uponthe end of the conductor, as shown in Fig. 3, with the inner end thereofoverlapping the forward end 10 of the cloth covering. The clip is thenclamped tightly about the end of the conductor, as shown in Fig. 4, thenotched and interengaging edges 9 of the clip being pressed together, asshown in said figure. This clip is clamped tightly in position, so thatthe bare ends of the wires are firmly gripped, as well as the end 10 ofthe cloth covering. The covering is thus prevented from slipping awayfrom the end, and the fine wires are firmly clamped together. TheV-shaped notches in the opposite edges of the clip insure the said edgescoming squarely together edge to edge and without overlapping when beingclamped in place. This clamping is preferably accomplished in a suitablepress arranged for the purpose. When the end of the conductor has beenso prepared, a drop of molten solder is placed within the bore 11 of thesleeve of the tip, and the end of the conductor is inserted therein. Thesolder (indicated by 12 in Fig. 5) will then serve to fill in at andabout the end of the conductor and clip and about the sides of the clip,as shown in Fig. 5, and will serve to mechanically and electricallyconnect the tip with the cord. The bore of the sleeve is preferablyslightly larger than the conductor, as shown in Fig. 5, and may bereamed out slightly at its outer end 13, so that the end of thetipsleeve will not abrade the. covering of the conductor. The amount ofthe solder placed in the sleeve is preferably limited, so that it willnot fiow above or beyond the end of the clamping-clip 8, as shown inFig. 5.

While the invention has been described with particular reference to thedetails of construction, it is apparent that various modifications maybe made without departing from the principle thereof and I therefore donot wish to be limited to the precise embodiment herein shown; but,

Having thus described my invention, what I do claim, and desire tosecure by Letters Patent, is

1. The combination with a conductor having an insulating-coveringstripped for ashort distance back from the end thereof, of a sheetmetalclip clamped around the bared end, of the conductor and overlapping thecovering so as to bind it in position upon the conductor, and a metallictip having a hollow sleeve to receive a small amount of solder intowhich the end of said conductor with the clip is inserted, whereby thesaid parts are all soldered together and electrically and mechanicallyconnected, substantially as described.

2. The combination with a conductor having an insulating-coveringstripped from the end thereof a short distance, a sheet-metal clipclamped about the same and having interengaging notches in its opposedmeeting edges, said clip overlapping the end of the covering to bind itin place, a tip having a hollow sleeve slipped over said end of theconductor and the clip and soldered thereto, substantially as described.

3. The combination with a conductor having an insulating-covering, thebare conductor projecting beyond the end of the covering ashortdistance, of a sheet-metal clip clamped about the ends of the conductorand overlapping the covering so as to prevent it from slipping back uponthe conductor, the opposed meeting edges of said clip' being providedwith interengaging V-shaped notches, and a metallic tip having a hollowsleeve slipped over the end of the conductor and the clip and solderedthereto, substantially as described.

4:. The combination with a conductor hav-' ing an insulated covering, ofa sheet-metal clip clamped around the conductor and overlapping thecovering to bind it in position, a rigid metallic tip provided with ahollow sleeve slipped over the end of the conductor and soldered theretoand with a pin formed integral with said sleeve and of reduced diameterto enable it to be readily connected to a suitable binding-post or otherpart, substantially as described.

of the covering to grip the same and hold it in position when the clipis clamped in place, and a tip having a hollow sleeve placed over theend of the conductor and clip and soldered thereto, the inner edge ofthe sleeveopening being rounded to prevent abrasion of the covering,substantially as described.

6. In a cord-terminal, the combination with a conductor consisting of aplurality of fine wires, of a sheet-metal clip clamped about the end ofthe conductor to bind said wires together, and a tip having a hollowsleeve slipped over the said clip and soldered thereto, said tip havingalso a portion adapted to be secured in the aperture of a suitablebinding-post, substantially as described.

having an insulating-covering, of a sheetmetal clip clamped about thebared end of the conductor tobind said fine wires together, said clipalso overlapping the insulating-covering and serving to clamp the samein place to prevent its slipping back upon the conductor, a tip having ahollow sleeve into which the said conductor end and clip are inserted,and solder within the sleeve to electrically and mechanically connectthe parts together, substantially as described.

8. In a cord-tip, the combination with a flexible conductor having aninsulating-covering, of means to bind the covering in place upon thebared end of the conductor to prevent its slipping back, and a rigid tiphaving a hollow sleeve and a pin of reduced diameter formed integralwith the sleeve, said sleeve being slipped over the said end of theconductor and soldered theretoand the said pin forming a ready means forconnecting the conductor in the electric circuit, substantially asdescribed.

9. The combination with a conductor having an insulated covering, of asheet-metal clip clamped about the bared end of the conductor andoverlapping the cloth covering to bind the same in place to prevent itsslipping back, a tip having a hollow sleeve fitting over the clip andconductor end, solder within the sleeve to mechanically and electricallyconnect the said parts together, the inner edge of the sleeve beingrounded to prevent abrasion of the covering of the conductor, the tiphaving a pin of reduced diameter formed integral with the sleeve andserving to permit the tip to be readily connected with a binding-post orother object, substantially as described.
